🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by blocking L-type calcium channels in the smooth muscle cells of blood vessels. Calcium is needed for these muscles to contract. By blocking calcium entry, this medicine causes the muscles to relax, which widens the blood vessels. This widening, called vasodilation, lowers blood pressure and improves blood flow to the heart. In angina, the improved blood flow and reduced workload on the heart help prevent chest pain.
